In some Occult and similar writings, an archdemon (also spelled archdaemon) is a spiritual entity, prominent in the infernal hierarchy as a leader of the infernal host. Essentially, the archdemons are the evil counterparts of the archangels.
Archdemons are described as the leaders of demonic hosts, just as archangels lead choirs of angels.
Historically, what an archdemon is and the names of those demons has varied greatly over time. Based upon the writings of Saint Paul (Col. 1:16; Eph. 1:21) the angelic court had been constructed by Pseudo-Dionysius the Areopagite and comprised nine orders of angels with three orders each to three hierarchies. The First Hierarchy: Seraphim, Cherubim and Thrones. The Second Hierarchy: Dominions, Principalities and Powers. ( The Scriptures mentioned above are out of context for this particular article. Those Scriptures speak about how the God of Israel made all terrerestrial and non terrestrial things for the man humans call the Christ and how he used this person to build them. Meaning, all things on this planet and on other planets (governments and authorities included), belong to this particular man. The God of Israel told this man to make these things. And when he made them, they were for himself. Hence, all things are for the Christ. Also, those Scriptures say that this Christ is more powerful and more prominent than any human or non human could ever be. This includes earthly and non earthly kings. That is what those Scriptures pertain to.....Candace S. Williams).
In the Occult tradition, there is controversy regarding which demons should be classed as archdemons. During different ages, some demons were historically "promoted" to archdemons, others were completely forgotten, and new ones were created. In ancient Jewish lore, pagan gods of neighboring cultures were classed as extremely pernicious in order to protect Jews from worshiping them; therefore, Ba'al and Astarte were among the worst enemies of God. During the Middle Ages these characterizations were no longer important, but still persisted. New ones emerged, mostly revolving around Satan and the Antichrist.
